IVF Pregnancy Data and Statistics - Infertility Solutions P.C.
(data compiled 12/15/2014)
We participate in national reporting of IVF data as administered by the Center for Disease Control (CDC) and required by the Federal government, but not in the registry of the American Society of Reproductive Medicine's Society for Advanced Reproductive Technologies (SART). We feel that the value of registry data is limited because it lumps conventional IVF together with IVM and Minimal Stimulation IVF. Patients are divided among all these types of cycles. The majority of our patients utilize these gentler approaches. These variant IVF cycles are much easier on the patient and less expensive, but overall, have a lower pregnancy rate.
The data reported below reflect conventional IVF only. Results for IVM and for Minimal Stimulation IVF (Mini-IVF or Mini-stim IVF) are reported elsewhere on this web site. The techniques are different and are recommended for different patient populations. We began to recommend the use of these techniques to many of our patients starting in 2010.
If a program offers IVM or Mini-stim IVF, it changes the potential pregnancy rate for traditional IVF in that program. Most of our best candidates for getting pregnant with traditional IVF choose to try IVM or Mini-stim IVF first since they are easier for the patient to do and less expensive if the patients are self-pay. Many of the patients who don't first try IVM or Mini-stim IVF or fail to get pregnant with these techniques may intrinsically be more difficult to get pregnant in the first place. These are then the patients who undertake IVF.
Summary data is expressed in terms of pregnancy rate per IVF embryo transfer. Most of the time, embryos are produced during an IVF cycle, but the problem is to get them to implant and become babies. Two types pregnancies are highlighted- clinical pregnancies (tissue or ultrasound evidence of pregnancy including tubal pregnancies), and ongoing/delivered pregnancies (these pregnancies have delivered or have a high probability of delivering). These two types of pregnancy rates provide different kinds of information. The ongoing/delivered pregnancy rate provides the most useful prognostic information for patients considering a program. The clinical pregnancy rate is more a reflection of the laboratory competence of the program since many pregnancy losses of clinical pregnancies reflect patient characteristics (e.g., ectopic pregnancy).
Summary data for women under age 35 is emphasized, because less patient selection takes place in this age category. Our program does not reject informed patients on the basis of age or decreased ovarian reserve (elevated FSH levels or very low AMH levels). In fact, we have a major interest in providing care for such patients. This may adversely effect our pregnancy rates compared to programs which do select patients, but we have had many wonderful pregnancies in patients rejected by other programs. In fact, SART requires the following statement when quoting program statistics: "A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic."
